To enable fast CAN response, I need to use SBL to load MCU1_0 image (either AUTOSAR or TI-RTOS).
boot_app_mcu_rtos is the demo app in SDK release for the early CAN response implementation. The boot app inside can be used to boot other cores in MAIN domain.
But the boot app reads the MAIN domain core images from OSPI flash. In my case, the MAIN domain core images may reside in eMMC.
How can I adapt this demo to achieve loading MAIN domain core images from eMMC(or SD)?
The u-boot is widely used across different platforms and different device vendors, the rich device/function supports are very useful.
We can use u-boot to achieve loading MAIN domain cores from eMMC or SD card. Either SPL or u-boot can be used.
Here is an example based on SDK V7.3. It is validated with TDA4VM EVM.
The boot flow which is achieved with the following patches can be figured as below:
There are two patches for mcusw:
patch 1: This patch is an adaption of running the default demo.
Please adapt the PATH inside to match your environment setup.

2.17.1
Steps for running the default demo:
1. use the build_boot-app-mcu-rtos_release.sh to build MCU1_0 image.
2. use the makemulticore_j721e.sh to build multicore images used in this demo
3. use the constructappimageshlos.sh to create HLOS images. In this demo, we are using prebuilt images in the SDK.
4. use flash_ospi_boot_main_demo.sh to flash the above images to OSPI flash.
----------------------------------------------------------------------------------
With the patch 1 above, we can run the SDK default demo with TDA4VM EVM. Now can use patch2 to do the u-boot-spl loading via boot_app.
patch 2: this patch is based on patch 1.

2.17.1
Steps to run:
1) clean the mcusw binaries, build the boot_app_mcu_rtos via build_boot-app-mcu-rtos_release.sh
2) build the u-boot-spl via rebuild_ubootspl.sh
3) use the constructappimageshlos.sh to create u-boot-spl appimage.
4) use flash_ospi_boot_u-boot-spl.sh to flash the binaries into OSPI flash
There are other details we should take care of. Such as the building of cust_sbl, flash_programmer, etc.
